If some of you haven't seen some of my post before I have a M19 that hasn't been working and have been trying to repair it. The original problem was that I could only get one shot off before all the gas releases. But after buying a new air seal part number 27, Because my original was broken I am now able to shoot maybe 5 rounds but have to pull the slide back to shoot before all the gas releases. Any ideas? Also my gas chamber appears to be resisting when I try to slide it ever since putting in the new air seal. Any help will be appreciated.

How are the springs that go with the air nozzle? Those can affect the travel of the air nozzle. Also your hammer might not be resetting its causing all the gas to expel. These are just problems I have had with the m19
